i have a bb 7100i and i tried to install opera mini 4.2 on it but it says error starting operette$2dhifi: Class 'javax.microedition.io.file.FileConnection ' not found i dont have a data plan as i use boost unlimited i did the download to computer then transfer to device via usb link with blackberry manager 4.2 can someone please help

Well I got it working I forgot to unzip the files on my cpu but then I deleted the service books and added the boostberry service books and now when I try to download an app it says opera mini wants to invoke the browser and then it says that the service books aren't there so now what do I do
